Reusable universal silicone covers The practical set has 6 different sizes with which you can seal cans, bottles, cups, glasses and bowls airtight. They are stackable and keep your food fresh for longer. The blue silicone cover is tightly sealed and leak-proof, so you can even store liquids. The lid can be easily cleaned under running water. The material is food-safe and reusable. It is flexibly stretchable so that it also fits on square containers despite its round shape. You can use the fresh lids in the fridge, in the microwave and even in the dishwasher. The lid is environmentally friendly and saves money, as you no longer need cling film.
